Everyone goes to Fred Meyer. Well, almost anyone.
You can get clothes, shoes, house supplies, garden supplies, food and much much more.
As a college student I can tell you that Fred Meyer is our local mall. Go there and be sure to meet some nice people.
Be sure to check out the clearance sections. Even the clearance meat section is ok (just freeze the meet).
And if you must, use the self checkout.. its faster.
Overall it is not less expensive than any other place to buy things in town, but you will run into more people if you go here.
